Types of attention

Precautions contents

Insulation inspection of the motor

Insulation inspection of the motor should be made for the initial use of the motor, reusing after long-term placing when the motor is used or given regular inspection to avoid damaging the AC frequency vector inverters due to the insulation failure of machine winding, motor connection must be separated with the AC frequency vector inverters when insulation inspection is made; it is suggested to use megameter with 550V voltage type and guarantee the insulation resistance detected can’t be smaller than 5MΩ.

2

Thermal protection of the motor

Make sure to adjust relevant parameter value of motor protection in the AC frequency vector inverters or install thermal relay before the motor to protect the motor when the rated capacity of the selected motor doesn’t match with that of the inverter, particularly when the rated power of the AC frequency vector inverters are bigger than that of the motor.

Change three- phase input to two-phase input

This AC frequency vector inverters can provide 0Hz~400Hz output frequency. If the customer wants to make operation above 50 Hz, please take the endurance of the mechanical device into consideration. The setting for hopping frequency in the AC frequency vector inverters can be used to avoid mechanical resonance point of the load device which might be met by the AC frequency vector inverter sat some locations of output frequency. Compared with the operation of power frequency, the temperature rise, noise and vibration of the motor will increase slightly because the output voltage of the AC frequency vector inverters PWM wave. If the side the AC frequency vector inverters has capacitance improving the power factor or voltage dependent resistor for lighting protection, it will cause instant overcurrent of the AC frequency vector inverters or damage the AC frequency vector inverters because the output voltage of the AC frequency vector inverters is PWM wave. Please don’t use it. If contactor between the power supply and input end of the AC frequency vector inverters is installed, then it won’t allow this contactor to control the start and stop of the inverter. If it is necessary to use this contactor to control the start and stop of the inverter, the interval can’t be bigger than one hour. Frequent charge-discharge easily shortens the service life of the capacitor in the AC frequency vector inverters. If switching element such as contactor installed between output terminal and the motor, it should be guaranteed that the switching operation of the AC frequency vector inverters should be made without output. Or it easily causes the module damage in the inverter. It is improper to use PT200 AC frequency vector inverters by and the voltage range stipulated in this manual; or it easily causes the device damage in the inverter. If it is necessary, please use corresponding rising and dropping equipment to make transformation disposal. Don’t change three-phase AC frequency vector inverters of PT 200 to two-phase for use. Or it may cause breakdown or damage the inverter.

The AC frequency vector inverters has protection device for lighting strike and overcurrent; and it has certain self-defensive ability for the inductive thunder. The customer should install protection device before the AC frequency vector inverters at frequent occurrence of the lightning. It is necessary to use it via derating in the region where the altitude is above 1000m due to the weakening cooling effect of the AC frequency vector inverters caused by thin air. Please make a technology consulting to our company for such a condition. Please consult our company if it is necessary for the customer to use the connection method beyond the suggestions provided in this manual, like DC bus. It may cause explosion when the electrolytic capacitor of main circuit and printed board burn. And the burning of plastic parts will cause poisonous gas. Please dispose it as industrial refuse. 1) Standard adaptive motor is asynchronous induction like a quadrupole squirrel cage. If it is not the above motor, please select the AC frequency vector inverters based on the rated current of the motor. 2) Cooling fan 3) Zx67y non-variable frequency motor and rotor spindle is connected with the same axis; cooling effect of the fan reduces when the rotate speed reduces; therefore, install powerful cooling fan or replace variable frequency motor when the motor is too hot. 3)The AC frequency vector inverters has been installed with standard parameter of adaptive motor; it is necessary to make parameter identification or modify default value according to practical situation to correspond with the actual value; or it may affect the operation effect or protection performance. 4) short circuit in the cable or motor will cause the alarm of the AC frequency vector inverters or even explosion of the motor, so please make a short-circuit test of insulation for the motor with initial installation; and it is necessary to make such a test in daily maintenance. Notice: make sure to completely disconnect the AC frequency vector inverters with the part required to be testing when such a test is made. 1)Never connect alternating current power supply with terminals like U, V and W for output end of the inverter. 2)The panel must be fixed and locked before electrifying in order to avoid personal injury caused by harmful components like internal capacitance. 3)Tasks such as wiring and inspection can’t be made after the power is connected. 4)After the electrifying of this device, please don’t touch its interior circuit and component to avoid electric shock hazard. 5)Don’t touch the circuit board or any component in the motor within five minutes shown on keyboard after the power is off; what is more, the meter should be used to confirm the capacitance in the motor has been discharged and then the task in the motor can be made; or it may have hazard of electric shock. 6)Electrostatic on human body will seriously affect MOS field effect transistor; don’t use your hand to touch any internal component such as printed circuit board and IGBT without anti-

3-6 Wiring precautions ※ Don’t install absorption apparatus of static capacitance or resistance capacitance at the U, V and W output terminal of the inverter. The input power supply of the AC frequency vector inverters must be off when the motor is changed. ※ Don’t drop the metal chip or thread residue into the AC frequency vector inverters when the wiring is made, or the AC frequency vector inverters may have fault due to this. ※ The motor or power supply of power frequency can be changed only after the AC frequency vector inverters stops outputting. ※ It should consider installing absorption apparatus of surging when the electromagnetic contactor and relay is near to the AC frequency vector inverters in order to reduce the influence of the electromagnetic interference. ※ External control line of the AC frequency vector inverters must have isolating device or adopt shielded wire. ※ Cable for signal of input order should have independent routing beside shieldling; and it is better to be far away main circuit wiring. ※ The maximal distance between the AC frequency vector inverters and motor should be within 50m when the carrier frequency is smaller than3KHz; and such a distance should be shortened when the carrier frequency is bigger than 4KHz; and it is better for this wiring to be laid in metal pipe. ※ When peripheral equipment (filter, electric reactor)is installed on the inverter, it should firstly use 1000 V megameter to measure its insulation resistance to the ground and it should be guaranteed it is no less than megohm. ※ Please don’t close the power supply under the condition of frequent start of the inverter; control terminal or keyboard or RS 485 must be used to operate the order to make start-stop operation so that it can’t destroy the rectifier bridge. ※ Don’t connect AC input power with output terminals of inverter: U, V 32

and W. In order to avoid the accident, ground terminal ( ) must be connected to the ground reliably (ground impedance should be less than , or leakage will appear. Choice for specification of wiring diameter should be according to related stipulation of National Electric Code when main circuit wiring is made. Electric motor capacity should be equal to or less than the capacity of the inverter.

3-7 Redundant circuit It will cause serious halt loss or other sudden failures due to the fault or tripping of the inverter. In order to avoid such a condition appears, please increase the following circuit backup for the sake of safety. Notice: redundant circuit should be confirmed in advance and its operation feature should be tested in advance to guarantee the consistence between phase sequence of power frequency and variable frequency.

Before Connect the power supply with the variable-frequency inverter, please firstly confirm the voltage of AC input power is within the scope of rated input voltage of variable-frequency inverter. Connect the power supply with the input terminal R, S and T of variablefrequency inverter. Select proper control method of rotation.

Chart 5-2 control method of rotation

Chapter 5

Example: voltage input of analog (P01.00=1,P01.03=1 or 2)+ control operation of the terminal(P06.01=1、P06.02=2); Frequency order is given by terminal AI1/AI2 and terminal DI2 and DI3 control forward and reversal rotation. Example: speed regulation of keyboard(P01.01=0, P01.03=7)+ reward and reversal switch operation of the keyboard(P07.03=1) The frequency is preset by the increase of clockwise rotation and the decrease of counterclockwise rotation of the keyboard encoder; FWD/REV of operation keyboard change the forward and reversal rotation. ※ Empty running and check of speed regulation. ※ Confirm the set of the lowest and highest output frequency. ※ Inspection of inching control. ※ Affirm the acceleration and deceleration time. ※ Connect up the motor. ※ Operate with low speed and inspect the rotation direction of the motor. ※ Inspect whether the display and output during all operation processes is correct.

Chapter 6

6-1. List of function parameter Function of PT200 series AC frequency vector inverters can be divided into 15 groups, namely P01~P15 according to the function; and every function group includes several function codes. The function code adopts three-level menu; for example, P08.08 means the eighth function code in P08 function group ; and P15 is the manufacturer’s function parameter and the user has no right to visit the parameter in this group. In order to make convenience for the setting of function code, group number of the function, number of function code and parameter of function code respectively corresponds with the first-level menu, the secondary menu and threelevel menu when the operation panel is used for operation. 1. manual for the content in the line of menu is as following: NUMBER in the first line: it is the serial number for this function code in the whole function code; meanwhile, it also shows the register address for the communication. CODE in the second line: it is the serial number for the parameter group of the function and parameter. DESCRIBING LED/OLED KEYBOARD DISPLAY in the third line: it is the detailed description of this function parameter. SETTING RANGE in the fourth line: it is the effective setting range of the function parameter and it is shown on OLED liquid crystal screen of the operation panel. FACTORY SETTING in the fifth line: it is the original set value for the function parameter when it leaves the factory; ALTERATION in the sixth line: it is the alternative attributive of the function parameter (i.e. whether it allows alternation and alternating condition); and the manual is as follow: “◇” shows the set value of the parameter can be alternated whenever the AC frequency vector inverters is stopped or operated; “□”shows the set value of the parameter can’t be alternated when the AC frequency vector inverters operated; “■” shows the value of the parameter is actual record value of the detection; and it can’t be changed; ( the AC frequency vector inverters has made an automatic check and restriction on alternative attributive of every parameter and it can help the user to avoid wrong alternation.) 2. Parameter system is decimal system; if the parameter is shown via hexadecimal, every data is independent mutually when the parameter is edited; value range of partial bits can be hexadecimal (0~F). 3. Factory setting shows the value after the parameter of the function code is updated when the operation of recovering factory parameter; parameter or record 44

Chapter 6

manual of function parameter

value of actual detection can’t be updated. 4. In order to protect the parameter more effectively, the AC frequency vector inverters provides password protection for the function code. After the user PRG password (namely, parameter for user password P07.00 is not 0) is set, the system will firstly enter into the state of user password authentication when the user press to enter into the editing state of the function code; and then what is shown is 0.0.0.0.0.; the operator must input user password correctly, or the user can’t enter. It is unnecessary to input manufacturer’s password correctly for the parameter zone set the manufacturer. (warning: the user can’t try to change the parameter set by the manufacturer; if the parameter is not set properly, it will easily cause the abnormal work or even destroy of the AC frequency vector inverters). The user password can be changed randomly under the condition that the password protection is unlocked; the user password is subject to the value input last. Setting P07.00 to 0 can cancel the user password; if P07.00 is not 0 when electrify, then it shows the parameter is protected by password. 5. Function of user password also follows the above principle when the serial communication is used to change the parameter of the function code. 6-1-1.Menu grouping Code

7-2. Introduction of EMC standard Based on the requirement of national standard GB/T12668.3,AC frequency vector inverter should meet the requirement of electromagnetic interference and anti-electromagnetic interference. The existing products of our company implements the latest international standard: IEC/EN61800-3:2004 ( Adjustable speed electrical power drive systems part 3:EMC requirements and specific test methods ) and national standard GB/T12668.3. IEC/EN61800-3 mainly inspects AC frequency vector inverter from electromagnetic interference and anti-electromagnetic interference. Electromagnetic interference makes test on the radiated interference, conducted interference and harmonic interference of AC frequency vector inverter (for civil AC frequency vector inverter). anti-electromagnetic interference mainly makes test on conducted immunity, radiated susceptibility, SURGE, quick and sudden EFT, ESD immunity and immunity at the bottom of power supply of AC frequency vector inverter (specific test project includes : 1. Test on immunity for temporary reduction, interruption and change of AC frequency vector inverter; 2. Test on the immunity at the breach of commutation; 3. Test on the immunity of harmonic wave input; 4. Test on the change of input frequency; 5. Test on imbalance of input voltage; 6. Test on immunity of input voltage ). The test is made according to the strict requirement of the above IEC/EN61800-3; products of our company are installed and used based on the guidance shown in 7.3 and they will have good electromagnetic compatibility under normal industrial environment.

Installation notes: 1)ground lead of AC frequency vector inverter and other electrical products should be connected with the ground well; 2)Input and output power line for the motive power of AC frequency vector inverter and signal line of weak current (like control wiring) should not be laid horizontally and lay them vertically if necessary. 3)power line for the output of AC frequency vector inverter is suggested to use shield cable or shielding power line of steel tube; and the shielding layer should be connected with ground reliably; leading wire for equipment disturbed is suggested to use shielding control line with twisted pair and the shielding layer should be connected with ground reliably ; 4)It is required to install output filter or electric reactor for the motor whose cable length is more than 100m. 7-3-3. Solution for the interference of surrounding electromagnetic equipment on AC frequency vector inverter Generally speaking, the reason for causing electromagnetic effect on AC frequency vector inverter is there is a lot of relays, contactors or electromagnetic brakes surrounding AC frequency vector inverter; the following methods is suggested to use when AC frequency vector inverter is disturbed by them and operates wrongly: 1) install surge suppression on the device giving interference; 2) Install filter on the input terminal of AC frequency vector inverter, please refer to 7.3.6 for operation detail; 3) Use shielding cable for control signal line and leading wire for detection circuit of AC frequency vector inverter and connect the shielding layer to the ground reliably.

7-3-4. Solution for the interference of AC frequency vector inverter on its surrounding electromagnetic equipment the noise in this part is divided into two types: one is the radiated interference of AC frequency vector inverter; and the other is the conducted interference of AC frequency vector inverter; the interference makes the surrounding electrical equipment have electromagnetic or electrostatic induction; then the interference can further make the device have wrong operation. Please refer to the following solutions for different interferences: 1) generally speaking, meter, receiver and sensor used for measuring has weak signal; and they are easy to interfere and cause wrong operation when they are near to AC frequency vector inverter or in the same control cabinet with AC frequency vector inverter; it is suggested to use the following methods to solve it: be away from the interference as far as possible; don’t lay the signal line and power line horizontally; in particular, don’t bind them together; signal line and power line uses shielding cable and connects with the ground well; add ferrite 66

bead to the output side of AC frequency vector inverter (blanketing frequency should be within 30~1000MHz) and roll 2-3 rings; EMC output filter can be installed for worse condition. 2) When the equipment disturbed and AC frequency vector inverter uses the same power supply, it will also cause conducted interference; if the methods mentioned above can’t eliminate the interference, then install EMC filter between AC frequency vector inverter and power supply (please refer to 7.3.6 for detail of type operation ) . 3)Independent grounding of external equipment can eliminate the interference caused by leak current which is caused by the grounding wire of AC frequency vector inverter when they share the ground together.

7-3-6. Precautions for installing EMC input filter at the input terminal of the power supply : 1)Notice: rated value must be strictly followed when the filter is sued; mental case ground of filter should be connect with metal ground of installation cabinet because filter belongs to I electrical equipment; moreover, it should have good continuousness of electric, conduction , or it may have electric shock hazard or seriously affect EMC effect; it is discovered via EMC test that filter ground and ground at PE terminal of AC frequency vector inverter should be connected to the same public ground, or it will seriously affect EMC effect. 67

7-3-5. Leakage current and disposal Leakage current of AC frequency vector inverter has two types: one is leakage current for the ground; and the other in leakage current among lines. 1) Factors affecting leakage current for ground and solution: The wire and the ground has distributed capacitance; the bigger the distributed capacitance, the bigger the leakage current; effectively shorten the distance between AC frequency vector inverter and motor to reduce the distributed capacitance. The bigger the carrier frequency, the bigger the leakage current. Reduce carrier frequency to reduce the leakage current. However, reducing carrier frequency can cause the increase of motor noise; please pay attention to installing electric reactor is also an effective way to solve the leakage current. leakage current will increase with the increase of loop current; as a result, corresponding leakage current will be big when the motor power is large. 2)Factors affecting leakage current among lines and solution: Output wirings have distributed capacitance; if the current passing through the circuit includes higher harmonic, then it is very likely to cause resonance and then result in leakage current. At this moment, if thermal relay is used, it may make it have wrong action. The solution is to reduce carrier frequency or install output reactor. It is suggested not to install thermal relay before the motor when AC frequency vector inverter is used. And use the protective function for overcurrent of electron of AC frequency vector inverter.
